Yes, we are back in production of the exquisite H.D. 4-element Abbe Orthoscopic oculars that have earned an outstanding reputation over the years. In cooperation with our associate firm Ohi Optical in Japan, these Phase II oculars reach new highs in optical performance. The new refined multi-coatings, introduced in late 2013, produce the brightest, sharpest images ever! Some of you may remember Ohi and University Optics introduced the first multi-coated telescope ocular over 50 years ago. The lenses in our famous Circle-T "volcano top" orthos were an Ohi product.
If you're looking for oculars so wide you can see both of your ears in the field of view, these are not for you. I, on the other hand, you are after scalpel-sharl lunar and planetary detail, these oculars will equal or exceed the performance of any 5 to 8 element ocular on the market costing three, four, or five times as much.
